To all whom 'it may; Gomera .le it known that l, Lima K. SNE-LL, a citizen o the United States, end "a resident of Detroit, in the eonnty l viiayne and State of Miehiganyhaye inrentefl a new anal improved Support for Extra Tires., which the following is a specification.

lThis invention relates to a support for extra tires of motor vehicles; and Sonie of its objects are to provide means whereby the weer on the rubber of the tire eansefi by direct Contact of any oi the supporting may beavoifleel; to pro elements tb'erewit i -vide `means whereby the may be conveniently placed in or reinoveal from position, and whereby it may be 'securely held whiie in position; and te improve the oonstruotion of tire supports generally.

This invention eensists in a support llaving a plurality of Contacts arranged to en,-

witli the rini that carries the tire, one or more of-the Cont ets being adjustable, preferably by tlireafleel ineens, whereby the rim and tire may be conveniently and idly secured in position. y

The invent-ion also eonsists'in the various details of construction shown, rieseribed anfl partieulariy pointed. out `in the elainis.

in the drawings, l) lgure l is a r'eer eleif'a tion of an' embodiment of my inventien wherein two tires are earriecl by the saine support, the tire nearest the observer being' partly broken away. is a sectionon the broken line 2--2 of Figi. AFig. 3 is a fragmentary section on the line -3 oi' Fig. 2.

Similar reference characters refer to like parts throughout 'he several views ln the embodiment shown, the dashed line l indicates the ontline oi thel rear of a well known type of *vehicle body; and 2 riesigL natos the side bars of the chassis, the rear ends of the latter of which may be shaped to receive the eneis of a cross-piece ,preierably tubular', by which the side are joined. This cross-niece bears the weight of the rear encl of the eliassisancl rests at its mid-portion'upon the cross spring 5, beingA secured thereto by clamping bolts 6 that may be U-shaped. The entls of the spring may be supported in any desired manner. f

Extending npwarly, rearwardly' and inwarly -(in respect to a "vertical plane ofii eine' ee. ser".

through the longitnrlin'ai axis of the ve hiele) from the enfle of the cross-bar fi are the members' l0 {pre'erably ros) the threaded lower enfle o' which may be sbonldered at il anni passed through aline peru orations 'inthe ends 3 of the side bars 2, being secured therein by the nuts l2. The

Lipper end of each of the 4rocio is extended rearwardly in a substantially horizontal clireetion, as indicated at 13, and may be prof yiiied. with the outwardly 'turned Contact portions le and 15, the distance between which is prefeably somewhat greater than therein. Passing through the ,slot is a bolt 'the rear end of which may be threaded vinto the base 2li ,of a rearwardly extending snp-porting member 25; the contacting snrfaees of the supporting member and. flange Zi may be ronghened at 26 to ailord an efieetive gripping engagement. lt will be observed that thev slot allows thefmeinber to be adjusted Avertically .in respect to the block. The n'ieinber 25 tially horizontally at 28 and is perforated and threaded at points in its length, corresponding to the distance between the Contact portions le anil l5, to receive the 'hand screws 29, having the Contact points 304 '.fcnnierl integrally therewith or otherwise connected thereto. Each of the latter preferably comprises a laterally extending lever `arm 3l, the enter enel of which is shapedto forni a hand grip 32 and a restricted neck 32%; and it is desirable to makethe lengths of the lever arms suoli that the hand grips may be brought into close proximity to each other and looked by a padlock 34. The ii1eiiiliei-2li-25 may be provided'with a. limit sten 25, similar to the`st0ps 16 heretofore deseribe.

lt is obvious that, were the-contact surfaces 14 ancllancl the member 25 supporteclii tinted relation to each other, a tire and rim' oi' a wheel niightbe slippecltherejexteneci snbstany over, after which the corresponding hand screw 29 could be extended to engage the inner surface ofthe rim and clamp the latter and the tire rigidly in position. The brace member 35 is therefore provided. As shown, this/r veinher is substantially ringshaped, being formed of an angie iron haV- ing a flange 36 to which the three supporting members are secured by the rivets 37; while the bracing member may be other than ring-shaped (for example, triangular or T- shaped), the form shown is desirable because of appearance, and also because its unobstructed center allows ready 'access to a tool-box, fuel tank Lor other element (not shown) often carried on the rear of the chassis. Also, while it is desirable to ar range the brace in a plane between the two.

sets of contact points, in order to secure most efficient bracing, it may be placed elsewhere.

In use the tir-e539 are placed over the contact points la or l5, the rims resting thereon, after which the hand screws are Vex'- tended to engage and clamp the rim. Va rious forms of rims may be used; that shown includes the ribs 40 -(Fig. 2) that serve to form an annular groove upon its inner face in which the contact points and the ends of the hand screws are received; the groove might, however, be formed in the Contact point itself, in which case the rim might have a single rib corresponding to the said groove. It will be seen thatJ when the rim and tire are supported in this manner, thel wear on the rubber of the binding straps and ,other contacting supporting elements conmonly used is entirely avoided, and that both .of the tires are supported on a rigid member having no joints, whereby a support is formed in which the liability of ailure andthe expense of construction is small.

It will befnoted that all variations in size and shape of the rim are compensated 'for by the three-point support when a screw is provided for adjusting one of the contacts. While itis desirable toplace the support at the .rear ofthe vehicle, it is clear that it i may be located elsewhere, and that it may be carried by portions of the vehicle other than gthe sprlngs. ltV is also clear that many,

changes may-be made-in the specific details of'construction without departing from the spirit of my invention. I do not, therefore, wish .to be limited otherwise than as indicated by the subjoined claims.. f
